Diagnosis. Clistopyga lopezrichinii may be distinguished from all other species of the C. diazi species group by the combination of the following characters: mesosoma with reddish areas ( Figs 6C, 6 D–E); genal orbit widely black, without a triangular white mark at ventral third; propodeum entirely black; hind leg with coxa brown, femur brown with a yellow apical spot; clypeal suture slightly curved ( Fig. 6A ); metapleuron about 1.8× as long as high; submetapleural carina strong, present on anterior 0.7 ( Fig. 2D ); ovipositor and ovipositor sheath about 1.5× and 1.4× as long as hind tibia respectively ( Fig. 6G ).

Description. Female: Body length 6.0 mm (without ovipositor). Fore wing length 4.7 mm.

Head ( Figs 6A, 6B ). In dorsal view, slightly constricted behind eyes. Gena smooth and shiny with sparse setiferous punctures, in dorsal view about 0.35× as long as eye ( Fig. 6B ), in frontal view almost straight and moderately constricted below eyes. Frons smooth and shiny with sparse setiferous punctures. Vertex smooth and shiny, with isolated setiferous punctures, a few shallow rugae below median ocellus and a median shallow furrow between lateral ocelli. Posterior ocellus separated from eye about 0.8× its maximum diameter. Distance between hind ocelli about 1.4× maximum diameter of posterior ocellus. Occipital carina complete. Face with moderately close setiferous punctures, distance between punctures less than twice the diameter of punctures. Clypeal suture very slightly curved ( Fig. 6A ). Clypeus 1.8× as broad as medially long, slightly convex in dorsal half, flat in ventral half, with apical margin straight. Clypeal tentorial pits conspicuous. Malar space 1.1× as long as basal mandibular width, with a narrow granulate stripe between eye and mandible. Antenna with 22 flagellomeres, first flagellomere about 5.6× as long as wide.

Mesosoma ( Figs 2D , 6 C–E). Pronotum shiny, mostly smooth, with fine and scattered setiferous punctures in upper posterior part. Epomia present, straight, reaching the anterior submarginal depression of the pronotum. Mesoscutum weakly and densely punctate crenulate. Notauli very strongly impressed anteriorly, reaching at least 0.5 of length of mesoscutum ( Fig. 6D ). Mesopleuron shiny, with moderately sparse setiferous punctures, except in posterior part under speculum, punctures denser towards ventral part ( Fig. 6C ). Epicnemial carina strong, reaching slightly below the centre of pronotum. Metapleuron shiny, with uniformly moderately dense setiferous punctures, 1.8× as long as high. Submetapleural carina strong, present on anterior 0.7 ( Fig. 2D ). Propodeum densely and finely transversally strigose, with moderately dense fine setiferous punctures laterally ( Fig. 6E ), in dorsal view 1.25× as long as medially wide. Propodeal spiracle slightly above groove separating propodeum and metapleuron, continuity of groove not interrupted by spiracle ( Fig. 6E ). Hind leg with femur about 3.3× as long as high, about as long as tibia. Fore wing with vein cu-a slightly basal to Rs & M; vein 2 rs-m about 0.6× as long as abscissa of M between 2 rs-m and 2 m-cu; abscissa of Cu 1 between 1 m-cu and Cu 1 a 2.1× as long as Cu 1 b. Hind wing with vein cu-a about 0.3× as long as abscissa of Cu 1 between M and cu-a; vein cu-a reclivous, abscissa of Cu 1 vertical and straight; distal abscissa of Cu 1 well pigmented.

Metasoma ( Figs 6 F–G). Tergite I about 1.1× as long as posteriorly broad, shiny, with wide and relatively dense setiferous punctures laterally; distance between punctures distinctly shorter than the diameter of each puncture; spiracle near its basal 0.4; lateromedian longitudinal carinae weak, reaching about 0.4 of length of tergite; lateral longitudinal carinae weak and complete. Sternite I extending back about 0.5 of length of tergite. Tergite II 0.8× as long as posteriorly broad, central region very densely punctate; remaining tergites densely and strongly punctate (Fig, 6F), punctures slightly weaker beyond tergite V. Ovipositor slender, evenly up-curved at distal 0.3, 1.5× as long as hind tibia ( Fig. 6G ). Ovipositor sheath about 1.4× as long as hind tibia, length of setae on average about 1.0× the sheath basal width. Ventral margin of ovipositor sheath basally with numerous very small denticles.

Colouration ( Figs 1D , 6 ). Head mostly black, with inner orbits, clypeus, ventral part of gena and mandibles yellowish, also with a U shaped yellowish spot on lower face adjacent to clypeus ( Figs 6 A–B); antenna blackish brown, ventrally pallid proximally, pedicel and scape ventrally and apically lighter. Mesosoma reddish brown except the following black areas: propleuron, most of pronotum except dorsolateral corners, median area of median lobe and median area of lateral lobes of mesoscutum, axillae ( Fig. 6D ), propodeum and upper edge of mesopleuron; anterolateral edges of mesoscutum with yellowish markings ( Fig. 6C ). Metasoma with tergite I dark reddish brown, tergite II dark reddish brown turning lighter apically, with yellowish marks antero-laterally, remainder of tergites dark reddish brown turning lighter apically ( Figs 6 F–G); ovipositor reddish-brown; ovipositor sheath darkened, almost black. Fore and mid legs predominantly yellowish, coxae with small brown marks, trochanters with brown markings basally; femora and tibiae brownish dorsally and ventrally, lateral sides yellowish, tarsomeres brown. Hind leg with coxa brown, trochanter brown basally and yellowish apically, trochantellus yellowish, femur brown with a yellow apical spot, tibia brown with a transverse yellowish band, tarsomeres brown. Wings hyaline, pterostigma brown ( Fig. 1D ).

Male: unknown.

Biology: This species has been reared from cocoons of the bagworms Oiketicus kirbyi (Guilding) ( Blanchard 1941; Esquivel 1950) and Oiketicus platensis (Berg) ( De Santis & Esquivel 1966; De Santis 1967) ( Lepidoptera , Psychidae ).

Material examined. Holotype. Argentina: 1 ♀, Alto de Sierra, XI–1940, s/bicho de cesto, Ichneumonoglypta lopez-mansillae Blnchd , cotipo, det E. E. Blanchard; 320; Ichneumonoglypta lopez-richinii Lectotypus Townes 1966 ( IMYZA).

Remarks. Previous to the formal description in 1941, Blanchard (1940) mentioned Ichneumonoglypta lopezrichinii (page 21) and Ichneumonoglypta lopez-mansillae (page 34) without any formal description, so the names are considered nomina nuda ( Townes and Townes 1966). In the 1941 description of Ichneumonoglypta lopez-richinii , he designates a holotype whose data are exactly coincident with the specimen studied here. However, in that specimen there is not a holotype label, but a cotype label written by Banchard, but curiously in the original description no other specimens were reported. In 1951 Townes and Townes synonymised Ichneumonoglypta with Clistopyga and probably later, when they were preparing the catalogue and reclassification of the Neotropic Ichneumonidae ( Townes & Townes 1966) , they labelled this specimen as lectotype, but never formally designated it as such.

Given this situation and considering that Blanchard did not mention any other specimen and that the label data of the specimen exactly match those mentioned in his publication, we consider the studied specimen in this paper as the holotype described by Blanchard.

Distribution: Argentina, Brazil.
